ProblemFourB( [12;3 4], 5) should return (2,3) and (1,4) c. Design an algorithm that can be called with ProblemFourC that uses one of the data structures we've discussed so far to find the Nth smallest number that takes the form i. Example ProblemFourC(0) returns 1, ProblemFourC(1) returns 7, and so forth.
